the y-intercept is the value of y when x = 0, linear equation
I cannot read your g(x)
i have hard time understanding slope like work. can this be explained?
slope is the change in y divided by the change in x over the same period
for 2 points (x1,y1) and (x2,y2) slope is the gradient/steepness of the line
in the sketch as you move from A to B what is the rate of change ? this is the slope.
change in y with change in x as a ratio
need more or are you ok now?
the direction is important when substituting the values.
K, I think it would be A. then.
